Installation / Setup
The setup of the datalogger involves installing the AK-75X software on a PC, connecting the IR interface to the computer’s serial port, and ensuring the correct serial port settings. The datalogger should be positioned so that its IR interface faces the connected IR interface on the PC for scanning. Users must ensure that no two dataloggers with the same address are scanned simultaneously. The setup includes naming the datalogger, selecting measurements, setting sampling rates, and defining start and end conditions for measurements. Alarm thresholds and units can be configured, and the setup is sent to the datalogger. Measurements are started and stopped via icons, with LED indicators showing status. External connections include an alarm output with a voltage limit, and thermocouple connections require specific wiring.
Operation
To operate the datalogger, first set up the PC by installing the AK-75X software and connecting the IR interface to the computer’s serial port. Use the software to verify the correct serial port settings. Position the datalogger’s IR interface facing the PC’s IR interface and use the software’s scan function to detect the datalogger. Set the time and date by transferring them from the PC to the datalogger. Configure the datalogger by naming it, selecting measurements, sampling rate, start and end of measurements, and setting alarms if needed. Send the setup to the datalogger and start measurements using the software. The green LED will indicate active measurements. To stop, use the stop command, which will be acknowledged by a red LED flash. Data can be read and processed using the software, which allows exporting to text or Excel files.
Troubleshooting & Error Codes

Safety & Warnings
Do not exceed 30V for input voltage and 20V for alarm output. Do not exceed the operating temperature range of -40°F to 185°F (-40°C to +85°C). The IR link operating range is 32°F to 185°F (0°C to 85°C). Ensure the IR window is clean. Using the AK-75X software in Instantaneous Measurement Mode will significantly reduce battery life. Do not scan two dataloggers programmed at the same address simultaneously. Fast sampling rates will reduce battery life. Alarm usage will reduce battery life due to flashing LEDs. When replacing the battery in Model 750, replace the seal to maintain IP68 protection.
